What can be called a source program?
Editor to share with you what can be called the source program, I believe that most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to understand it!
A program written in a high-level programming language is called a "source program", which cannot be run directly. The source program is relative to the target code and executable code; the source program is a code program written in assembly language and high-level language, which is a series of human-readable computer language instructions.
A program written in a high-level programming language is called a source program, and the source program cannot be run directly. To use a high-level language on a computer, you must call the compiler or interpreter of that language into your computer's memory before you can use the high-level language.
Source program (also known as source code) refers to an uncompiled text file written according to certain programming language specifications, which is a series of human-readable computer language instructions. In modern programming languages, source code can be in the form of books or tapes, but the most commonly used format is text files, a typical format designed to compile computer programs. The ultimate goal of computer source code is to translate human-readable text into binary instructions that can be executed by the computer. this process is called compilation and is done through the compiler.
Program use
The source program is generally many lines of English software that can be opened in notepad and written in programming language.
The source program can only be run after it is compiled into the target program. The general target program can no longer be modified.
The software installed on our computers are all target programs. Except for the source programs of the scripting language, other source programs cannot be run directly.
Proponents of open source software believe that source programs should be provided to users so that they can modify them themselves, which is conducive to the development of the software industry. Opponents feel that this is not conducive to the protection of copyright.
If you don't know how to program, the source program can ignore it. It does not affect the normal use.
As a special part of the software, the source code may be included in one or more files. A program does not have to be written in the same format of source code. For example, if a program is supported by the C language library, it can be written in C language, while the other part can be written in assembly language in order to achieve high efficiency.
More complex software, the source program files can reach thousands of. In order to reduce the complexity, we must introduce a system that can describe the relationship between the source code and how to compile correctly. In this context, the revision control system (RCS) was born and became one of the necessary tools for developers to revise the code.
There is another combination: the source code is written and compiled on different platforms, and the technical term is software migration.
The above is all the content of this article "what can be called a source program". Thank you for reading! I believe we all have a certain understanding, hope to share the content to help you, if you want to learn more knowledge, welcome to follow the industry information channel!
